Vertical expansion tank 200L AQUATICA (779129). For automatic water supply system operation, a closed diaphragm-type expansion tank with a pneumatic accumulator of appropriate volume must be installed, as pressure switches can only work in conjunction with an expansion tank. An expansion tank is a device integrated into the water supply system to maintain the required pressure, ensuring the system is always ready to operate under stable pressure. Functions: Accumulation of water under constant pressure, allowing the pump to start not immediately upon water draw from the system, but only as the liquid volume (pressure) in the expansion tank decreases; Protection of the water supply system from water hammer that occurs during initial pump starts or high water draw; Storage of reserve water in the water supply system. Technical specifications: Metal body made of painted alloy steel; The membrane used in the expansion tank is made of synthetic ethylene-propylene rubber EPDM. Operating conditions: Maximum ambient temperature: +40°C; Maximum temperature of accumulated liquid
